JOURNAL BOX AND MOUNTING.

Specification of Letters Patent.

Griginal application filed April 27, 1920, Serial No. 376,971.latentlihflfimfiw, dated March 1, 1921. Divided and this application meaDecember 14, 1920. S eha1 No. 430,680.

To all whom it concern:

Be it known that I, Lao 'K. Srarronn, a citizen of the United States,residing at New York, in the county of Bronx and State of New York, haveinvented new and useful .use in connection with anti-frictional bearingmeansbetween a car wheel journal and the journal box therefor. In suchconstructions, it is absolutely necessary that the bearings, andconsequently the box carrying the bearings, be at all times retained inlongitudinal alignment with the journal. Otherwise the bearings wouldcreate friction between the journals and the bdxes which would renderthe bearings defective, subjectthe same to breakage, and cause injury tobe inflicted to both the journal and to the box. As is well-known inrailway construetions, it is frequent that the rail on one side of atrack is disposed at a greater or less elevation than the rail on theother side of the track, and as the wheels of the rolling stock must atall times follow the rails the truck frame or mounting for the journal,

box must necessarily be of a character which will yield laterally on thebox to compensate forsuch irregularities in the rails of the track'andnot influence the journal box, with respect to its longitudinalalignment on the axle, to prevent'unnecessary friction between theroller bearings, the journal and the box, or damage which wouldotherwise be inflioted'to such parts. i

It is therefore to be considered the primary object of the presentinvention to roduce a. journal box which carries a-nt1- rictionalrollers that engage with the jourr'ial or spindle or" the axis for thewheels of rolling stock, and a mounting therefor which is.

susceptible to lateral angular movements n the box without. ailectingthe longitudinal alignment of the box on the journal.

It is a still further object of the invention to produce journal box forthe journals on the wheels of railway rolling stock and a mountingtherefor, in which fulcrum means is provided between the mounting, andthe box which will permit the mounting to assume angular" positions withrespect to the box, when thawheels of the rolling stock pass overirregular track surfaces, and wherein the degree ot the angle assumed bythe mounting will be limited by means between the mountin and the box.

It is a still further objectto produce a ournal box which carriesanti-frictional hearings to enga e with the journal on the wheel of arailway rolling stock, wherein a fulcrum engagement between the top ofthe box and the to of the mounting is produced,

and wherein t e means that secure the box will appear as t e nature ofthe invention is better understood, may be accomplished by aconstruction, combination and operative association of parts, such as isdisclosed b the drawingswhich accompany andwhic form part of thisapplication.

In the drawings Figure 1 is side elevation of the improvement partsbeing broken away and parts being in section.

Figure 2 is a side elevation illustrating a slight modification.

Figure 3 is a front elevation of the box shown in Figure 1, with partsbroken away and parts in section. Figure 4 is an elevation lookingtoward the front of a journal box of a slightly moditioned on amountingsuch as 1s commonly employed for supporting. the journals of 'fiedconstruction, showing the same pom-- it will be seen thatanti'frictional rollers at face of the wheel, an

bearings and the mounting of said box on the truck in a manner whichwill permit of a limiting rocking or lateral angular positions of themounting on the truck when. irregularities with respect .to the heightof the rails on the track are encountered. All such devices which havecome under my observation have been worked out in accordance with thetheory as applied to the anti-frictional bearings between the spindle of'a shaft and the ordinary vehicle wheel,

in which spring supports are provided be tween the axles and the body ofthe vehicle. In railway rolling stock, the journal or spindle of theaxle is rejected beyond the the truck frame or hearing support for thejournal boxes and for the body of the rolling stock, while yieldablewith respect to the said body, are not susceptible to a slight swingingor lateral movement on the boxes. Consequently, the-longitudinalalignment of the roller bearings in the boxes and the journals withwhich the same engage are materially interfered with, creating frictionandd'amage to parts, and rendering the roller bearings not onlydefective but absolutely inoperative so that the same are positivelyimpractical and detrimental in the use for which they are designed.

As the description progresses, it will'be readily seen by those havingknowledge of the art to which this invention relates that I havesuccessfully overcome the deficiencies above referred to, and that alsoI have provided means whereby friction between the journal and" thejournal box of railway stock is reduced to such an extent that the caror coach may carry a far greatrir weight without liability of damage tothe wheels, journals, journal boxes and supports therefor, than hasheretofore been a'ccom 'ilished.

Referring. now to the drawings in detail, the numeral 1 designates thejournal or spindle end (if an ordinary axle for the wheels of railwayrolling stock. The journal 1, of course, projects beyond the outer faceof the wheel (not shown), and has its spindle end received in a journalbox 2.

By reference to Figure 3 of the drawings,

are disposed in circular series between a bushing 5 that is swaged onthe journal I spindle 6, and a bushing 7 that is swaged to the innerface of the journal box. Of course, other arrangements ofanti-frictional bearings may be providedbetween the box and spindle. v

The box. in the showing, in Figures 1 and 3 of the ,drawings is designedfor use on freight carrying cars. The box 2, at its top. and at thecenter thereof has a lateral projection in the nature of :1 lug 8. andthis 1,4.os,oeo

and at its top and bottom. portions is provided with outstanding ears 9and 10 respectively, and each of the said ears has an elongated opening11 therethrough. The sides of the box, between the ears 9 and 10 areformed With ribs 12 respectively. These ribs, from the central. portion13 thereof are inclined outwardly, providing angle walls or shoulders 14which terminate in the end walls provided by the outstanding ears 10.Thus the centralportions of the confronting faces of the ribs 12 arepointed.

The mounting for the box is in the nature of the usual frame. In thisconnection, it is thought desirable to state that except for the journalbox, no changes are made in the car construction. The upper bar 15 ofthe mounting rests directly on the lug 8, while the lower bar 16 of themounting is disposed a slight, but-'sutiicient distance from the bottomof the box to permit of a lateral swinging motion or yielding of themount-' ing on the box without permitting the lower bar 16 being broughtinto contact with the box, or otherwise interfering with such movementof the mounting.

Passing through the upperand lower bars of the mounting, are bolts 17.The respective pairs of bolts pass through the elongated'openings 11 inthe ears 9 and 10 and are received in the. channel provided be tween theribs 12. On the bolts, and having their ends contacting with. the bars15 and 16 respectively of the mounting, are sleeves 18 respectively, thesaid sleeves contacting or being only slightly spaced away from thecentral pointed portions 13 of the angle ribs 12, The btilts 17 areengaged by nuts 19,

The upper hfir pf the mounting has a fulcrum engagement with the, top ofthe journal box, incident'fto the engagement of the said bar withthe-Jug 8. The means which secures the boat-to the mounting, that is, ofcourse, the brilts and the sleeves thereon, being arranged in thechannels between the ribs 12, haven fulcrum engagement with the points13 of; the said ribs. Thus the mounting may rock or yield laterally withrespect to the journal box, and such rocking or yielding will be limitedby the contacting engagement of the sleeves 18 with the angle walls 14cf the ribs 12. When the mounting is at its extreme angular positions onthe journal box, one side of each of the sleeves 18 will be in contactwith either the upper or 1 0 lower angle surface onbne of the ribs 12,

and the opposite side of the said sleeves will he in contact with thediagonal o posite angle surface on the other r1b12. hus when in suchposition, both sides of the sleeves are engaged by the ribs, but atopposite points.

The sleeves relieve the bolts from undue strain.

ImFigure 2 of the drawings, the journal 1 is received in a journal box21 of a slightly 380 diilerent construction from that above described.lhe journal box 2 has its sides provided with spaced ribs 12' arrangedin opposed pairs. The ribshuve their central portions hickened upontheir ,lill'lfil confronting faces and are beveled or arranged atopposite outward inclinations from the central portions l3 thus providedthe angle walls to the opposite sides of the central points 13",beinrindiciitcd by? the numeral 1%. topper the box, bets on the spaced pairsof is provided with a projection in the nature of u lug 8" l .ch isrounded from its center to its edges, T he mounting for the box has itsends rovided with yolres, whose?- depending patrol elarms 18 arereceived between the spacodpairs of ribs 12, the upper element 15' ofthe yoke resting on the lug 8", and the lower ends of the yoke, whichproject s suitable distance below the -ournel box 2 being connected by uplate 16. With this construction, the ears 9 and 10 are dispensed with,as are also the untifrictional rollers which surround thcbolts thatconnect the plates 15 and 16 in the mounting previously described.

Iii the remaining figures of the drawings, the journal box 20 has itssides provided with the spaced pairs of ribs 21, whose inner faces. aredisposed at opposite angles from the central point 22 therefor. The ribs21 are spaced a further distance apart than are the ribs 12, for thereason that the ribs 21 receive therebetween the flat side members 23 ofthe yoke 24 that is employed in the usual construction of truck frameson passenger coaches. The top of the box 20 has a. transverse crosssectionzrlly rounded lup, thereon, and the said top, at the sides of thelug are provided with upstanding flanges 25. Between these flanges, andresting on the fulcrumed lug 52 i, is the end of the equal iz'ing bar 26of the mountihg construction. T be lower bar 2'? of the mountingsecured, in the usual manner to the ends of the yoke 24, and is spacedfrom the bottom oi the journal box 20, as clearly disclosed by thedrawings, so that's rocking or lateral movement of the mounting on thebox will not be interfered with,

.ln both forms of my improvement, it will be noted, ample provision ismade for positively retaining the untidrictionel roller bearings carriedby the journal boxes in proper and positive engagement with the spindlesorjournuls of the wheel carrying axles, as well as the positivelongitudinal or parallel arrangement of the box with respectv to boththe journal spindle and the roller bearings. With my improvement, thewheel of the rolling stock will, at all times, and under all conditionsfollow the rails of the track, and as a consequence, the deficicn- "ciesabove recited are not only effectively overcome but the danger ofderailment which is always occasioned by the tread portions of theWheels of the rolling stock not positively ,engs ingthe heads of therails, is also eifective y overcome.

While I have illustrated and described a satisfactory embodiment of theimprovement as itnow appears to me, it is to be undcrstood thut suchdepartures may be made therefrom as fall within the scope of What isclaimed.

Having described the iifientlon, I claim 1..- In combination, a journalbox and a, mounting therefor, means on the journal box engaging themounting, and providing a fulcrum thercbetween, means assing through themounting and contacting the sides of the box for connecting the box tothe mounting, and means on the sides of the box at the opposite sides ofthe connecting means for engaging the latter for limiting the rockingmovement of the mounting on the box.

2. In combination, a, journal box and a mounting therefor, fulcrum meansbetween the upper surface of the journal box and the mounting, meanspassing through the mountpassing through the members constituting themounting and contacting with the sides of the boxfor securing the latteron the former, said box having its sides provided with s passage for thereception of said securing means, and the walls of said passage beingdisposed at an outward angle from the center thereof, as and for thepurpose set forth.

4. In combination, a journal box and a: mounting therefor, the latterincluding members which are arranged over and below the box, atransverse rounded lug on the top of the box contacting the upper memberof the mounting sud providing a fulcrum therebetween, ribs arranged inspaced pairs on the sides of the box, and having their l. 3. ll
